Abstract

The image reading method and the apparatus therefor of the present invention are characterized in that deviation in the optical axis due to changes in the magnification in the auxiliary scanning and main scanning directions are corrected by determining the optimal position of the slit. This allows the resultant images to be very clear-cut without blurs. Further, the slit positioning apparatus of the present invention is characterized in that the slit is positioned so that linear image light by the slit enters a suitable position of a linear sensor. This also allows the resultant images to be very clear-cut without blurs.
